Information

This information is part of the Modelica Standard Library maintained by the Modelica Association.

This component monitors the mass flow rate flowing from port_a to port_b. The sensor is ideal, i.e., it does not influence the fluid.

Parameters (3)

allowFlowReversal

Value: system.allowFlowReversal

Type: Boolean

Description: = true to allow flow reversal, false restricts to design direction (port_a -> port_b)

m_flow_nominal

Value: system.m_flow_nominal

Type: MassFlowRate (kg/s)

Description: Nominal value of m_flow = port_a.m_flow

m_flow_small

Value: if system.use_eps_Re then system.eps_m_flow * m_flow_nominal else system.m_flow_small

Type: MassFlowRate (kg/s)

Description: Regularization for bi-directional flow in the region |m_flow| < m_flow_small (m_flow_small > 0 required)

Connectors (3)

port_a

Type: FluidPort_a

Description: Fluid connector a (positive design flow direction is from port_a to port_b)

port_b

Type: FluidPort_b

Description: Fluid connector b (positive design flow direction is from port_a to port_b)

m_flow

Type: RealOutput

Description: Mass flow rate from port_a to port_b

Components (1)

system

Type: System

Description: System wide properties
